Operating System is abbreviated as?

• A. Operating System
• B. OPS
• C. O/S
• D. SYS

Answer: (A)

Abbreviations in IT often shorten terms to a few letters. For a computer’s main software layer, the term “Operating System” is normally written as OS or O/S, not left in full as words. This shorthand appears widely in documentation, command prompts, and tech discussions because it’s quick and unambiguous.

Among the options, the one that uses the actual abbreviation is the form that shows O/S. The full spelling “Operating System” is not an abbreviation, and the other short forms like OPS or SYS aren’t standard abbreviations for this term. So, the correct representation is the option that uses O/S.
